FRANCIS H. GULLEN, OF PITTSBURG, ASSIGNOR OF ONE-HALF TO THOMAS WALSH,OF ALLEGHENY, PENNSYLVANIA.

HAMMER.

SPECIFICATION forming part of Letters Patent No. 304,618, datedSeptember 2, 1884:.

Application filed March 22. 1884. (No model.)

To aZZ whom, it may concern:

Be it known that I, FRANCIS H. OULLEN, a subject of the Queen ofEngland, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inHammers, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to an improvement in hammers; and it consists in adevice attachable to the handle of a hammer, by means of which a nail,tack, or book can be driven, by the use of only one hand, as high up asthe hammer can be made to reach, dispensing with ladders or otherobjects to stand upon during the operation, as will be fully describedhereinafter.

Figure 1 is a side elevation of a hammer embodying my inventioncomplete. Fig. 2is a perspective of the sliding block and its at- Figs.3 and 4 are different views of the same device.

A represents thehandle of ahammer, around the lower end of which is aremovable band,B, of which the raised ends are held together by a screwor rivet, that serves at the same time as a pivot on which an arm, 0,moves toward and away from the handle. The arm 0 is placed at the sideof the handle, under the striking part of the head of the hammer, and isof alength to be even with the head when bent toward it. In the band B,between the handle and the pivoted arm, is secured a spring, H, thatbears against the arm and pushes it away from the hammer. On or near thefree end of the arm Gis a sliding block, D, that when adjusted, is heldin place by a screw. Under and fastened to the block D isafiat spring,E,

of the width of the block, and protruding from extends back under theblock D, and has its exposed ends slightly bent down. At the outer sideof the block D is another spring,G, secured by a screw, which spring isbent back upon itself close to the block.

The nail or tack to be driven is pushed into the slit Fin the spring E,its head held between the spring and the bottom of the block D. Thepoint of the nail or tack is held at the place where it is to enter, andthe hammer applied as usual. When a hooksuch as is used to hold gas orother pipes to walls-is to be driven, the hook is introduced between thespring G and the block, the shoulder on the hook pushed under the edgeof the block, and the blows of the hammer applied to drive it home. Theblows of the hammer falling on the block D, that is in contact with theobject to be driven, are as effectual as if applied directly.

A hammer provided with the described device will be found of value onmany occasions, and can be used with advantage for riveting in places ofdifficult access.

Having thus described my invention, I claim-- The combination of thehammer A with the pivoted spring-actuated arm 0, which is connected tothe outer end of a handle, the block D, that is adjustable backand forthupon the arm C, and a set-screw for securing it in place, the flatspring E, which is secured to the under side of the block for holdingthe nail, and the spring G, which is applied to the side of the block,substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANCIS H. OULLEN.
